Roland space echo 150

Hello all. Newb here looking for advice on my Roland Space echo. Its in 9-9.5 condition cosmetically. I went through it the best my capabilities would allow. I cleaned all the pots and jacks. I installed a new tape. I did not clean the pinch rollers or demagnetize it. Rollers look good and I am not sure how to demag. The tape rolls as it should. It produces echo but nothing as it should. I am willing to work on it more with guidance. I am willing to have it serviced. I am not sure where to take it. I am located in the Ann Arbor area in Michigan. Any advice would be appreciated. Thanks !

Could you be more specific? I have a RE-201 that had issues. Turned out the mode selector was messed up, possible soldering issues from the previous owner. Specifically, some modes worked and some did not. Took it to a local tech and he took the knob apart, cleaned it and re-soldered it. Also, I know echofix sells a cap replacement set. All I got, but hopefully it helps you or at least leads you in the right direction to getting it back and running.
